Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F3401CS are identified based on the following critical parameters that determine functional interchangeability:

Electrical Parameters (Must Match):

• Resistance value: 3.4 kOhms
• Tolerance: ±1%
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C minimum

Mechanical Parameters (Must Match):

• Package / Case: 2010 (5025 Metric)
• Physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm)
• Number of terminations: 2

Performance Parameters (Equal or Better):

• Power rating: 0.667W minimum (higher ratings acceptable)
• Composition: Thick Film
• RoHS compliance: ROHS3 or equivalent
• Moisture sensitivity: MSL 1 or better

The RMCF2010FT3K40 from Stackpole Electronics Inc meets all substitution criteria with identical electrical and mechanical specifications. The substitute part provides a higher power rating (0.75W vs. 0.667W), which represents an improvement in thermal margin without affecting circuit performance.

Parameter Comparison

Engineering Selection Recommendations

The RMCF2010FT3K40 is a direct functional equivalent to the RC5025F3401CS for applications requiring a 3.4 kOhms ±1% thick film chip resistor in 2010 package format.

Substitution Basis:

All critical electrical parameters match exactly: resistance value, tolerance, temperature coefficient, and operating temperature range. Mechanical compatibility is confirmed through identical package designation and physical footprint dimensions. Both parts maintain ROHS3 compliance and MSL 1 moisture sensitivity rating, ensuring equivalent environmental performance and regulatory status.

The substitute part provides a 0.083W increase in power rating (0.75W vs. 0.667W), which enhances thermal margin without introducing any circuit compatibility issues. The maximum seated height difference of 0.002" (0.04mm) remains within standard PCB assembly tolerances and does not affect placement or clearance.

Product Status Consideration:

Both the main part and substitute are classified as Active products with full manufacturing support and availability. The substitute part includes AEC-Q200 automotive qualification, which represents an additional quality assurance level beyond the base specification.

Frequently Asked Questions (FAQ)

Q: Can the RMCF2010FT3K40 be used as a direct replacement for RC5025F3401CS in existing designs?

A: Yes. The substitute part matches all critical electrical specifications (resistance, tolerance, temperature coefficient, operating range) and mechanical parameters (package, dimensions, terminations). No circuit redesign or validation is required for functional substitution.

Q: What is the significance of the higher power rating on the substitute part?

A: The RMCF2010FT3K40 is rated at 0.75W compared to the RC5025F3401CS at 0.667W. This represents improved thermal capability and does not create any compatibility issues. The substitute can safely handle the same or higher power dissipation without performance degradation.

Q: Are there packaging differences between these parts?

A: Both parts use the 2010 (5025 Metric) package with identical footprint dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm). The maximum seated height differs by 0.002" (0.04mm), which is within standard PCB assembly tolerances and does not affect placement or clearance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RC5025F3401CS and RMCF2010FT3K40 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. The substitute part additionally qualifies to AEC-Q200 automotive standards.

Q: What is the temperature coefficient and how does it affect substitution?

A: Both parts specify ±100ppm/°C temperature coefficient across the -55°C to 155°C operating range. This identical specification ensures equivalent resistance stability over temperature and confirms functional interchangeability.

Q: Can the substitute part be used in tape and reel packaging for automated assembly?

A: The RMCF2010FT3K40 is supplied in Tape & Reel (TR) packaging, which is standard for automated PCB assembly processes. The RC5025F3401CS packaging format should be verified against specific assembly requirements.
